Nine patients with the loin-pain/haematuria syndrome are described. The previously reported clinical features of severe recurrent loin pain and tenderness in young women, the relationship of symptoms to use of oral contraceptives, and the demonstration of intrarenal vascular abnormalities by angiography are confirmed. Histology revealed minor non-specific abnormalities, and electron microscopy showed fibrin in the afferent arteriole and in glomerular capillaries of one patient only. No diagnostic changes were found on renography. In all patients except one the heparin-thrombin clotting-time was abnormal, suggesting increased platelet activity or release and providing further evidence of a vascular disorder.

Loin pain may be a major presenting symptom in patients with glomerulonephritis. Most of these patients show an underlying focal and segmental proliferative glomeruloneyphritis and there may be associated deposits of IgA and Igg in the mesangium. In this group of patients, vascular lesions are often prominent in the absence of hypertension. Episodes of recurrent macroscopic hematuria also occur, but the pain cannot be attributed to colic due to blood clots in the ureter.

Twenty-two patients with intermittent loin pain thought to be typical of primary pelvic hydronephrosis but with normal appearances at standard excretion urography were subjected to diuretic urography using Frusemide-induced diuresis. If this was normal, acute urography was performed when the patient had pain. Abnormal appearances were shown in only 15 patients. In 4, only the erect films revealed the hydronephrosis. Dilatation occurred in response to a diuretic load in 9 and the abnormality was shown at the time of an attack of pain in 4. The hydronephrosis was shown only during the attack of pain in 2, a diuretic urogram having been normal. In 2 patients the nephrographic signs of acute obstruction were shown to be due to occlusion of the pelvi-ureteric junction at the time of an attack of pain. The importance of sequential examination, the value of erect films and acute urography are stressed.

Rheumatic manifestations are common and varied in infective endocarditis. We performed a retrospective case analysis on 87 patients with 93 episodes of infective endocarditis admitted to Flinders Medical Centre over an 11 year period (1980-1990). Disabling musculoskeletal symptoms and signs were documented in 22 (25%) of the patients. Thirteen patients developed severe or moderately severe low back pain during their illness, two with radiological evidence of a septic discitis or vertebral osteomyelitis. Two patients developed polyarthralgia/arthritis, four had septic arthritis (all with acute Staphylococcus aureus endocarditis), three developed severe loin pain, two acute gout, two had severe buttock pain and sacroiliac joint tenderness and two each developed disabling jaw/facial pain, neck/scapular pain and flank pain respectively. Five patients presented initially to the orthopaedic or rheumatological unit for management of their musculoskeletal symptoms. Four of seven patients with Streptococcus bovis endocarditis demonstrated prominent low back pain supporting a previously noted association between this organism and back symptoms. Furthermore, in one patient who had three separate episodes of endocarditis involving three different organisms, florid back symptoms were only seen in the infective episode involving Streptococcus bovis.

In a 6-year period, 9 patients were referred by their General Practitioners to the urology unit with a clinical diagnosis of renal colic but were subsequently found to have leaking abdominal aortic aneurysms (AAA). In all cases of loin pain, especially in the elderly patient, the possibility of a leaking abdominal aneurysm must be considered. If no intrinsic urological cause for the pain is found or patterns suggestive of ureteric obstruction are seen on urography, ultrasound examination of the aorta-iliac vessels should be performed. Magnetic resonance imaging (MRI) and computed tomography (CT) scans may be useful adjuncts to this investigation.

The current literature suggests that renal autotransplantation is nearly uniformly effective in controlling the severe and debilitating pain of the loin pain-hematuria syndrome (LPHS). However, we report two patients thought to have this syndrome in whom renal autotransplantation did not result in long-term control of pain. In case 1, autotransplantation resulted in immediate cessation of pain; however, the flank pain recurred 7 1/2 months later. The recurrent pain was also severe and debilitating, requiring narcotic medications for control. In case 2, autotransplantation of the left kidney resulted in chronic pain in the left pelvic area, the site of the autotransplanted kidney. In addition, the patient continued to experience chronic discomfort in the left flank and along the flank incision. One year after autotransplantation, the patient still requires multiple daily doses of narcotic medications for pain control. Our two patients represent the 13th and 14th reported patients subjected to renal autotransplantation for management of LPHS. They represent only the third and fourth reported patients with recurrence of pain after renal autotransplantation. Because studies with negative results are less likely to be reported in the literature than studies with positive results, it is possible that the literature overestimates the effectiveness of renal autotransplantation in the LPHS. To assess the true effectiveness of renal autotransplantation in LPHS, a survey of patients with LPHS who have undergone renal autotransplantation needs to be performed.

The loin pain-hematuria syndrome is a poorly understood constellation of symptoms consisting of persistent hematuria and intractable loin pain with negative comprehensive urological evaluation. The patients are severely debilitated by the pain and are usually dependent on narcotics. Various medical and surgical treatments have been tried unsuccessfully, ultimately leading to nephrectomy in many instances. The symptoms may subsequently occur contralaterally. Renal autotransplantation as a form of nephron-sparing denervation therapy for relief of pain was performed on 12 kidneys in 10 patients (2 bilaterally). Excluding 3 patients with followup of less than 1 year (all 3 are pain-free), 8 of the 9 autotransplantations have resulted in dramatic relief of pain, curtailment of narcotic use and return of the patient to normal daily function. Median followup was 43 months (range 15 to 53 months). The remaining patient had pain in the graft area necessitating transplant nephrectomy 4 months later. For patients severely affected by pain and narcotic dependence with this syndrome, renal autotransplantation may provide a nephron-sparing surgical solution.

Endometriosis and its complications are not uncommon in Malaysian women. Two cases of ureteric obstruction due to endometriosis are reported and the literature on ureteric obstruction and endometriosis reviewed. It is emphasized that the possibility of ureteric obstruction must be suspected when there is extensive endometriotic disease or if the patient presents with loin pain or pain on one side of the abdomen. Ultrasound scan of the kidneys and, if necessary, an intravenous pyelogram will have to be done on the slightest suspicion. Patients with endometriosis will have to be followed up until the menopause or even later if they are on hormone replacement therapy.

Twenty-five patients (seven male, 18 female) were diagnosed as having the loin pain and haematuria syndrome. Presenting symptoms were either loin pain alone or pain associated with macroscopic or microscopic haematuria, and were longstanding, having been present for mean of 9.3 years in males, and 10 years in females. Ten patients described symptoms of passing gravel or renal stones but these were only demonstrated radiologically in two patients. Investigation of all patients showed anatomically normal renal tracts, normal renal function, and no significant proteinuria. Phase-contrast microscopy during episodes of haematuria revealed dysmorphic red cells in all 10 patients studied. Renal biopsies were performed in 20 patients and showed no glomerular pathology, but arteriolar and arterial hyalinosis was seen in 13 of 20 (65 per cent), fibro-elastosis in larger vessels in eight of 20 (40 per cent) and red blood cells in tubules in 13 of 20 (65 per cent) patients. The histological appearance in vessels was similar to that seen in cyclosporin A nephrotoxicity and would be consistent with the hypothesis that regional vasospasm occurs in the cortical circulation. Haematological studies in 22 patients, when compared with age and sex matched controls, showed the presence of circulating platelet aggregates, elevation of plasma beta-thromboglobulin (p less than 0.001), and increased platelet aggregation in response to serotonin and ADP (p less than 0.05 and p less than 0.03, respectively). Plasma concentrations of D dimer (p less than 0.02) and C-reactive protein (p less than 0.03) were also significantly elevated in the patient group. There was no deterioration of renal function during a mean observation period of 3.7 years and no patients developed proteinuria. Treatment was largely supportive; seven patients with intractable loin pain underwent surgical denervation with the relief of pain in four.

In acute "primary" pyelonephritis (APP), kidney infection occurs despite normal urinary tract morphology. Typical features of APP are spiking fever and chills, loin pain, pyuria, bacteriuria, isolation of uropathogenic strains of E. coli, and specific renal CT scan images. APP may be atypical when lacking pain, or fever, or when urine cultures are negative, or when urinary bacteria do not exhibit characters of uropathogenicity, or when CT scan examination is negative. Such atypical features entail loss of time in diagnosis, and thereby delayed treatment and increased risk of cortical scar formation. However, they are virtually never observed simultaneously in a given patient.
